title:Linear time recognition of P4-indifference graphs
keywords:P4-indifference, algorithm, recognition
abstract:A graph is a P4-indifference graph if it admits an ordering < on its vertices such that every chordless path with vertices a, b, c, d and edges ab, bc, cd has a<b<c<d or d<c<b<a. We present a linear time recognition for these graphs.
